Abstract:
A cooling fan comprising a housing that connects to a chassis that is operable to support an electronic component. An axial duct runs through the housing. A blade assembly is rotatably disposed within the duct and comprises a plurality of fan blades that extend radially from a hub to a fan diameter. The axial duct has a chord length at least equal to the fan diameter. A motor assembly is disposed within the axial duct and coupled to said blade assembly. The cooling fan provides a cooling capacity of at least 1. 5 air horsepower per cubic inch volume of the cooling fan.
